Detailed Description

template<typename T, int N>
class lsst::geom::Extent< T, N >

A coordinate class intended to represent offsets and dimensions.

Much of the functionality of Extent is provided by its CRTP base class, ExtentBase.

See Operators on Point and Extent for mathematical operators on Extent.
